DELL N3000 User Manual

Managing General System Settings

To increase security, you can require authentication between the configured 

SNTP server and the SNTP client on the switch. Authentication is provided 

by Message Digest 5 (MD5). MD5 verifies the integrity of the 

communication and authenticates the origin of the communication.

The N3000/N4000 series switches support several different plug-in modules 

(also known as cards) for the expansion slots located on the back of the 

switch. For information about the slots and the supported modules, see 

"Hardware Overview" on page 91. You can preconfigure the card type prior to 

inserting it into the switch. 
Hot-swap is supported on the N3000/N4000 switch modules. However, the 

switch must be rebooted for the new module to be recognized after it is 

inserted.
Before inserting a new module into the expansion slot that was previously 

occupied by a different type of module, issue a no slot command from the 

CLI so that the switch can recognize the new module.
Once a module hs been recognized by the switch, its configuration is stored 

locally on the switch as the switch default. The module configuration appears 

in the running-config for informational purposes.
